Java Question

Reload log4j2 configuration on demand

I have my log4j2.xml config file set to be checked every 30 seconds:

<Configuration status="WARN" monitorInterval="30">
...
</Configuration>


Is it possible to programmatically tell log4j2 to check for changes in the configuration instead of having a timeout?

N.B. I don't want to programmatically load the configuration specifying the config file, I just want to tell log4j2 to check the config file that has been loaded before as if the monitorInterval expired.

Thanks!

Answer

It looks like I've found the solution:

((org.apache.logging.log4j.core.LoggerContext) LogManager.getContext(false)).reconfigure();

Does anyone see anything wrong/side-effects with this?
